ABSTRACT

The present invention relates to a gas balloon with floating height control ability, more particularly, a gas balloon  1  capable of floating in air by static buoyancy of gas, comprising balloon member  2  and weight control member  4  of the balloon; wherein the balloon member  2  comprises reinforcement coating layer  6,  silver coating layer  7  and outer surface fabric cloth  8  while said handle part  2   a  has magnetic plate  3  therein to control the weight of the balloon  1,  having large and small piece  5, 5   a.    
     The gas balloon  1  according to the invention can keep its floating height to a constant level by removing said large and small piece  5, 5   a  continuously to lead rising of the balloon  1,  especially, even in case the balloon  1  which is used for long term gradually falls down since it causes gas filled in the balloon member  2  flowing out of the member as time goes by, thus, induces loss of the static buoyancy of the member  2.

FIELD OF THE INVENTION

The present invention relates to a gas balloon having floating heightcontrol ability, more particularly, a gas balloon capable of floating inair by static buoyancy of gas, comprising balloon member and weightcontrol member of the balloon wherein the handle part is formedintegrally underneath of the balloon member.

BACKGROUND OF THE INVENTION

The present invention relates to a gas balloon having floating heightcontrol ability, more particularly, a gas balloon capable of floating inair by static buoyancy of gas, comprising balloon member and weightcontrol member of the balloon, wherein handle part is formed integrallyunderneath of the balloon member, wherein the balloon member comprisesreinforcement coating layer, silver foil coating layer and outer surfacefabric cloth while said handle part, the magnetic plate is layed insideit, and at the outer part, several magnetic pieces which the weight isdeferent from each other are attached to be attaching/detaching easily.

Such gas balloon can be controlled by its floating height by attachingor removing the magnetic pieces cutting-off piece along said dotted lineformed on the handle part of the balloon member, while the balloon isunder floating condition simultaneously. The gas balloon according tothe invention can keep its floating height to a constant level byremoving the large and small magnetic pieces on the weight controlmember continuously to lead rising of the balloon, especially, even incase the balloon which is used for long term gradually falls down sinceit causes gas filled in the balloon member flowing out of the member astime goes by, thus, induces loss of the static buoyancy of the member.

Conventionally, it is generally known that a balloon means a substancerising and floating by static buoyancy of gas filled in air bag of thesubstance made of cloth covered with rubber material (at present, mostlymade of synthetic resin such as PVC) without supply of power andincludes a heat balloon using hot air in the air bag heated by way ofburner and/or a gas balloon using hydrogen or helium gas. The balloonfurther includes a mooring balloon used to suspend the balloon to groundand/or ships with rope, a free balloon drifting in the air by persontook in the balloon, etc. based on the form of such air bag.

In recent years, among such mooring balloons, especially popular onecomprises a smaller balloon such as ad balloon and, in particular, asmall sized balloon in the form of toy balloon designed with variedcharacters and patterns is in the spotlight.

For instance, smaller balloons which have been often used in varioussports stadium, large scale entertainment stages for performance ofartists, moderate and small indoor party rooms and the like can bedirectly possessed by individuals took part with the observance, andalso enhance visual effect for them by floating numerous balloons withvaried colors at the same time and from a number of locations andkeeping them to desirable height.

However, in such case, each of the gas balloons does not carry the gasfilled in the balloon but discharges it out of the balloon as time goesby and, thus, does not keep the static buoyancy to a constant levelrequired to float the balloon. As a result, the respective gas balloonsgradually fall down and have different floating heights along to degreeof falling down, thereby, lead a problem of reduced visual effect.

SUMMARY OF THE INVENTION

In order to solve such problem, the present invention proposes animproved gas balloon comprising balloon member and weight control memberand has a purpose of conveniently controlling the floating height of thegas balloon in the air by detaching magnetic piece of said weightcontrol member formed at lower part of said balloon member,attaching/detaching sticker or magnetic piece while the balloon isfloating in the air, so that the present balloon can incite mood and/oratmosphere of various observances including meeting, game and so on tocoincide with them held in appropriate places such as indoor rooms andbe effectively utilized as an advertisement means.

The foregoing, as well as additional features and advantages of theinvention will be apparent from the following detailed description,which proceeds with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

FIG. 1 shows a perspective view of a gas balloon having floating heightcontrol ability with a weight control member of the magnetic piece forcontrolling the weight as decomposed from balloon member of the gasballoon according to the present invention, and FIG. 2 is across-sectional side view of the same gas balloon illustrated in FIG. 1.

Such gas balloon 1 which commonly comprises a handle part 2 a formed onlower central end of a balloon member 2 filled with floating gas toallow the balloon to float in the air by static buoyancy of said gas,characterized in that the handle part 2 a which is formed at the centrallower end of the balloon member, the magnet plate is layed, and areconnected and composed to be a weight control member 4 and also severallarge magnetic piece 5 and small magnetic piece 5 a are connected sothat to be easily detachable, said magnetic plate 3 is made of therubber magnet which is thin plate type and having an excellent elasticpower.

And also large magnet piece 5 and small magnet piece 5 a are composedwith thin rubber magnet having an excellent elastic power and are from0.2 g to 0.5 g in weight for the small size gas balloon 1.

Such balloon member 2 may be a spherical toy balloon capable of beingfilled with hydrogen or helium gas and formed of reinforcement coatinglayer 6, silver foil coating layer 7 and outer surface (fabric) cloth 8.

Compared to a common small balloon generally consisting of only silverfoil coating layer 7 and outer surface cloth 8, the gas balloon of thepresent invention has further a reinforcement coating layer 6 inside ofthe said silver foil coating layer 7 in a laminated form to ensuresafety and durability of the balloon.

Accordingly, by cutting the large and small piece 5 and 5 a graduallywith griping the handle part 2 a of weight control member 4, the largeand small piece 5 and 5 a reduces its weight and generates floatingpower equal to amount of the weight reduced by the large and small piece5 and 5 a, thereby makes the gas balloon 1 to rise in the air.

For example, the gas balloon 1 according to the present invention cancontrol its floating height to a desirable level by removing the largeand small piece 5 and 5 a of the weight control member 4, even when suchgas balloon 1 is used for long term and gradually falls down due to thegas filled in the balloon member flowing out of the member as time goesby, thus, inducing loss of the static buoyancy of the member.

Whenever several the balloons 1,1 . . . are flying in air at constantlevel, the user can continuously check the gas buoyancy of the balloonwith passage of time and repeatedly cut and remove the large and smallpiece 5 and 5 a of the weight control member 4 to control floatingheight of the balloon 1 to the constant level required dependent oncircumstantial atmosphere and/or places.

FIG. 3 shows the perspective view in the first embodiment of the presentinvention wherein cutting-off pieces of the weight control member isremoved, and FIG. 4 is a cross-sectional view of the FIG. 3 and theweight control member 14 is formed in the long band type, and pluralityof cutting-off pieces 10 are formed for controlling the floating powerof gas balloon 1 by cutting-off line 9 removing at the same time, fromthe lower part one or plurality of them.

Accordingly, cutting-off pieces 10 which are removed by an user whogrips the weight control member 14 and takes off the pieces 5, 5 a alongthe cutting-off line 9 can serve as a weight control part of the balloonmember 12. By such cutting-off pieces 10, the weight control member 14reduces its weight and generates floating power equal to amount of theweight reduced by the cutting-off pieces 10, thereby makes the gasballoon 11 to rise in the air.

As described above, the gas balloons 1, 11 comprising the balloonmembers 2, 12 and the weight control members 4, 14 according to thepresent invention have been described in detail by way of preferredembodiments which should not be construed to limit the scope; however,it is further understood by those skilled in the art that variouschanges and modifications, especially, in locations and/or shapes of theweight control members 4, 14 may be made in the invention withoutdeparting from the spirit and scope thereof.
